Question

The differential equation of all non-horizontal lines in a plane is

• A. $\frac{d^{2}y}{d{x}^2}=0$
• B. $\frac{d^{2}x}{d{y}^2}=0$
• C. $\frac{dy}{dx}=0$
• D. $\frac{dx}{dy}=0$

Answer 1

The correct option is A $\frac{d^{2}y}{d{x}^2}=0$

The differential equation of all non-horizontal line in a plane is $\frac{d^{2}y}{d{x}^2}=0$

Part $\left(A\right)$ is correct answer.
